Figure 6 is a combustion efficiency chart for natural gas fuel with power burners that shows the relationship between excess air, flue gas temperature, and combustion efficiency. As an example, tracing the Step 1 line, at 9% flue gas oxygen (equivalent to about 67% excess air as seen in the graph) and 500oF flue gas temperature rise, the corresponding combustion efficiency

01/01/2014 · The 320 MW natural gas fired boiler was modeled . installed in the steam boiler OP-210 with a capacity of 210·10 3. decreases in the flue gas flow direction, so that the length of the

How to Calculate Boiler Steam Flows | Hunker

The system architecture is the one shown in Figure 1 featuring Solar Thermal (ST) panels in series with a Heat Pump (HP), and in parallel with a natural gas CHP Internal Combustion Engine (ICE). A natural gas boiler further increases the water temperature in case of thermal demand peaks. The electricity and heating demand profiles, the delivery temperature (constant at 80°C), return temperature and DHN

Case Study: Optimization of an Industrial Steam Boiler

in heat lost due to the increased flue gas flowthus lowering the overall boiler fuel-to-steam efficiency. The table relates stack readings to boiler performance. On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be
